Examines the effects of cage size on stereotyped and normal locomotion and on other abnormal behaviors in singly caged animals, whether observed abnormal behaviors tend to co-occur, and if the development of an abnormal behavior repertoire leads to reduction in the number of normal behavior categories.

Demonstrates that categorization of speech sounds can be influenced by the phonetic structure of connected speech. (Editor/RK)

This article is concerned with the perceptual load in searching for a number of kinds of target which are presented for a fixed, short period of time. The aim is to establish data which any acceptable model of human information processing will need to fit. (Author)

Discusses two propositions about the preliminary stages of acoustic analysis and encoding in the absence of focal attention. (Editor/RK)

The recognition memory of eight-, ten-, and twelve-year-old children (n-108) was tested using an incidental learning technique. The children were required to categorize a set of word stimuli according to either a structural (presence or absence of the letter A in the word) or a semantic (identification of the word as the name of an animal or a…

Builds upon earlier experiments in an attempt to measure the interferences between simultaneous tasks and the effects of hypnotic dissociation in increasing or decreasing this interference, thus testing the validity of one or the other of two theoretical models. (Author/RK)

Presents three experiments that explore whether inescapable shock of long duration and moderate intensity (LoShk) produces an avoidance-escape deficit (called an interference effect) by causing animals to learn to respond less actively or by causing them to learn to be "helpless". (Editor)

Several experiments tested the occurrence of the "Kamin effect", i.e., the deficit in performance of an incompletely learned avoidance task, in terms of discrimination (choice) behavior by rats. (Editor/RK)

Repeated, isolated presentations of a stimulus typically reduce the subsequent ability of that cue to become an effective conditioned stimulus. This phenomenon is known as the latent inhibition effect. Four experiments investigate this effect. (Editor/RK)

If the N1 wave (amplitude component between 80-130 msec) does not serve as an index of an initial stimulus set stage of selection, the N1 amplitudes should be differentiated between channels whether the selection is based on pitch, spatial position, intensity, or cues that lead to an efficient rejection of unwanted information. This study…

The effects of real-world schemata on recognition of complex pictures were studied. Two kinds of pictures were used: pictures of objects forming real-world scenes and unorganized collections of the same objects. (Editor)

The Peterson and Peterson short-term memory paradigm (1959) involves an interpolated task with several potential dimensions from which interference may originate: similarity of items and vocalization. This research assesses the relative interference potency of each on material presented either aurally or visually. (Editor/RK)
